Yeah a wire strainer. A cheap one at the dollor store works fine.
I myself have always had trouble using glue or paint as the adhesive. Comes out uneven, but someone had shown me another method and I put his tutorial up on my website. I did a whole car with that stuff and it worked great. For an interior it will require a fair amount of masking but the results are worth it. Just let the adhesive dry before tapping it out. Here is a link to that tutorial.

Credit goes to a kid named 1ofakind. Only thing I would change is to make sure you paint the part the desired color before flocking, it will look alot better.
